Psychometric Properties of the Positive Mental Health Scale (PMH-Scale) in Peruvian Nursing Professionals.
Article in SAGE open nursing. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Positive mental health is a relevant protective construct for nursing professionals, who are frequently exposed to high emotional and occupational demands. However, brief and psychometrically sound instruments for assessing positive mental health in Peruvian nursing personnel remain limited. Objectives: To evaluate the psychometric properties of the Positive Mental Health Scale (PMH-Scale) in Peruvian nursing professionals. Method: Instrumental, quantitative, cross-sectional, and non-experimental study with 328 participants. The internal structure was analyzed using Confirmatory Factor Analysis (CFA). Reliability was assessed with Cronbach's α and McDonald's ω. Invariance was measured by sex, participation in religious activities, and the type of psychological care received. Convergent validity was examined in relation to optimism, life satisfaction, anxiety, and depression. Results: The one-dimensional model showed adequate fit (CFI = .978; TLI = .971; RMSEA = .072; SRMR = .027); Internal consistency was high (α = .93; ω = .94). Configural, metric, scalar, and strict invariance were sustained in the groups analyzed (ΔCFI ≤ .01). Correlations supported convergent validity (expected direction with optimism and life satisfaction; negative with anxiety and depression). Conclusions: The PMH-Scale is a concise, valid, and reliable instrument for screening for positive mental health in clinical environments characterized by high emotional demands, such as nursing. Its application can facilitate prompt monitoring and inform evidence-based interventions.
